TB_PrintScreen

This software is not for directly use in your development and it was finished in 2011 spring. It demonstrates one possible efficient way to build a print-screen software. Due to that I was a newbie in terms of design mode in 2011, so the codes are not so friendly in reading. You can mainly focus on the Main.cpp file in which many useful methods, routines are implemented. Hope you can get what you want here!

TB_PrintScreen

This software is not for directly use in your development. I finished it in 2011 spring. Now I share it to show all interested friends the best efficient way to build a print-screen software. In 2011, I was a college student and not familiar with design mode or even object-oriented development. But in it, some fantastic functions are implemented. Hope you can get what you want here!

ParseKit

Parse() is a comprehensive Delphi-based toolkit designed to streamline the entire process of compiler construction. By providing a unified API, it allows developers to define a custom programming language’s syntax and logic within a single configuration object. The system manages the complex transition from source text to native binaries.
